[0052] The core of the present invention is to provide a foldable electrical assembly table, which can not only meet the needs of placing electrical parts, but also can be transported without being affected by its large size.

[0053] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0054] Traditional electrical assembly tables require placement racks, which occupy a large amount of space in the height direction. This makes it inconvenient to carry the electrical assembly table due to its high center of gravity. If the placement racks are abandoned, the storage and placement of electrical parts will be affected.

[0055] Based on this, an embodiment of the present invention discloses a foldable electrical assembly table, which can change the spatial position of the placement rack by folding the placement rack, so that the placement of electrical parts can be met and the transportation will not be affected by the large volume during transportation.

[0056] like Figure 1 and Figure 2 As shown, the foldable electrical assembly table disclosed in the embodiment of the present invention includes an assembly table body, a placement rack 300 and a locking assembly.

[0057] The assembly table body may be similar to the structure of a conventional assembly table body, for example, it may include an assembly table top 100 and support legs 200. The support legs 200 are disposed below the assembly table top 100 to support the assembly table top 100.

[0058] One end of the rack 300 is hinged to one end of the assembly table body. Specifically, the rack 300 can be hinged to one end of the assembly table surface 100 so that the rack 300 can be switched between the use position and the stowed position around the hinge axis. It can be understood by those skilled in the art that the use position is the position of the rack 300 when it is in use, that is, the position when it is used to store electrical parts, and this position is usually located above the assembly table surface 100. The stowed position can be designed as needed and is not limited to a specific position. For example, it can be rotated to be laid flat on the upper surface of the assembly table surface 100, or it can be rotated to the bottom of the assembly table surface 100, as long as the height of the rack 300 can be reduced. When laid flat on the assembly table surface 100, the rack 300 can be supported by the assembly table surface 100 so that the rack 300 is kept in the stowed position; when rotated to the bottom of the assembly table surface 100, the weight of the rack 300 itself can be used to keep the rack 300 balanced.

[0059] The locking assembly includes a locking drive mechanism 400 and a locking docking assembly. The locking drive mechanism 400 is arranged on the assembly table body. The locking docking assembly includes a first locking member 700 and a second locking member 800. One of the first locking member 700 and the second locking member 800 is arranged on the placement rack 300, and the other is driven by the locking drive mechanism 400 to move.

[0060] When the first locking member 700 and the second locking member 800 cooperate with each other, the placement rack 300 is locked in the use position, that is, when the first locking member 700 and the second locking member 800 cooperate with each other, the placement rack 300 cannot continue to rotate, and then the placement rack 300 can be rotated to the use position, and then the locking drive mechanism 400 is used to drive the first locking member 700 and the second locking member 800 to cooperate with each other, so as to lock the placement rack 300 in the use position.

[0061] When the first locking member 700 and the second locking member 800 are disengaged, the rack 300 is unlocked and can swing to the stowed position. That is, when the first locking member 700 and the second locking member 800 are disengaged, the rack 300 loses the constraints of the first locking member 700 and the second locking member 800 and can continue to rotate, and then the rack 300 can be rotated to the stowed position.

[0062] The foldable electrical assembly table provided by the present invention hinges the placement rack 300 on the assembly table body through a hinge shaft, so that the placement rack 300 can rotate around the hinge shaft to change the position on the assembly table body. When the placement rack 300 is rotated to the use position, it can be used as a device for placing electrical parts. When it is not needed to be used as a device for placing electrical parts, the placement rack 300 can be rotated to the stowed position to change the space occupied by the placement rack 300 in the height direction, reduce the volume of the foldable electrical assembly table in height, and make it more convenient to carry. In order to keep the placement rack 300 in the use position and prevent it from rotating to the stowed position by itself during normal use, the foldable electrical assembly table is also provided with a locking assembly, and the placement rack 300 can be locked in the use position by the locking assembly to improve the safety of the use process. When the placement rack 300 needs to be stowed, it can be unlocked so that the placement rack 300 can be rotated to the stowed position to reduce the occupation of the height space and facilitate transportation.

[0063] In a specific embodiment of the present invention, one of the first locking member 700 and the second locking member 800 has a locking block, and the other has a locking slot for inserting the locking block. Figure 2 In the illustrated solution, the first locking member 700 has a block, and the second locking member 800 has a slot. Of course, the settings may also be reversed, for example, a slot is provided on the first locking member 700 and a block is provided on the second locking member 800.

[0064] The locking drive mechanism 400 can be used to drive the first locking member 700 to move, and fix the second locking member 800 on the placement rack 300. The first locking member 700 can also be fixed on the placement rack 300, and the locking drive mechanism 400 is used to drive the second locking member 800 to move. When the card block is inserted into the card slot, the swinging movement of the placement rack 300 around the hinge axis is locked. This is because when the placement rack 300 rotates around the hinge axis, the second locking member 800 will rotate with the placement rack 300 at the same time. Since the card block of the first locking member 700 is inserted into the card slot of the second locking member 800, when the second locking member 800 rotates, the card block of the first locking member 700 will limit the rotation of the second locking member 800, so the placement rack 300 cannot rotate and is constrained in the use position.

[0065] like Figure 3 and Figure 4 As shown, in a specific embodiment of the present invention, the locking drive mechanism 400 includes a first threaded rod 401 and a screw drive device, and the screw drive device is used to drive the first threaded rod 401 to rotate. The first threaded rod 401 is rotatably supported on the assembly table body, and specifically, can be supported on the assembly table surface 100 through a bearing.

[0066] The first locking member 700 has a screw hole threadedly matched with the first threaded rod 401, so that the first locking member 700 can be threadedly matched with the first threaded rod 401 to move along the axis of the first threaded rod 401 as the first threaded rod 401 rotates. It should be noted that the first locking member 700 and the first threaded rod 401 form a structure similar to a lead screw mechanism. In order to enable the first locking member 700 to move along the axis of the first threaded rod 401 when the first threaded rod 401 is rotated, the rotation of the first locking member 700 needs to be limited to prevent the first locking member 700 from rotating with the first threaded rod 401.

[0067] When the first locking member 700 moves to the first position along the first threaded rod 401, it cooperates with the second locking member 800, and when it moves to the second position along the first threaded rod 401, it disengages from the second locking member 800. By changing the rotation direction of the first threaded rod 401, the moving direction of the first locking member 700 can be changed, so that the first locking member 700 can reciprocate between the first position and the second position to drive the locking and unlocking of the first locking member 700 and the second locking member 800.

[0068] Furthermore, the screw drive device includes a worm 403 and a worm wheel 402. The worm 403 is rotatably supported on the assembly table body. Specifically, the worm 403 is rotatably supported on the assembly table surface 100 through a bearing. At least one end of the worm 403 protrudes from the assembly table body to facilitate driving the worm 403 to rotate through the protruding end. In order to make the rotation more convenient, a first rotating hand wheel 404 is provided at one end of the worm 403 protruding from the assembly table body. The first rotating hand wheel 404 has a larger outer diameter than the worm 403, so that the rotation of the worm 403 is easier to achieve.

[0069] The worm wheel 402 is coaxially arranged on the first threaded rod 401 and meshes with the worm 403. The worm 403 can be driven to rotate by the first rotating hand wheel 404. When the worm 403 rotates, the worm wheel 402 will rotate synchronously. Since the worm wheel 402 is coaxially arranged on the first threaded rod 401, the first threaded rod 401 will rotate synchronously with the worm wheel 402. As the first threaded rod 401 rotates, the first locking member 700 moves along the first threaded rod 401 between the first position and the second position to complete the locking and unlocking actions of the first locking member 700 and the second locking member 800.

[0070] In this embodiment, a worm gear mechanism is used as a screw driving device to drive the first threaded rod 401 to rotate. Since the worm gear mechanism has a large reduction ratio, a large torque can be generated by rotating the first rotating hand wheel 404, making it easier to rotate the first threaded rod 401.

[0071] In order to ensure the stability of the first locking member 700 when it moves between the first position and the second position along the first threaded rod 401, in this embodiment, a plurality of first threaded rods 401 can be arranged, for example, at least two first threaded rods 401 are arranged in parallel. The number of the locking docking assemblies is the same as that of the first threaded rods 401, and they correspond one to one, and each first threaded rod 401 is provided with a worm gear 402.

[0072] Taking the case where there are two first threaded rods 401 and the first locking member 700 is threadedly matched with the first threaded rod 401 as an example, the pitches of the two first threaded rods 401 can be designed to be the same, so that the first locking members 700 respectively matched with the two first threaded rods 401 have the same moving speed. It should be noted that even if the pitches of the two first threaded rods 401 are equal, if the rotation speeds of the two first threaded rods 401 are different, the two first locking members 700 will not have the same speed. In this embodiment, the structures of the two worm wheels 402 can be designed to be the same, so that when the worm 403 is rotated, the two worm wheels 402 can output the same rotation speed, that is, the two first threaded rods 401 output the same rotation speed, and finally ensure that the two first locking members 700 have the same moving speed, thereby ensuring that the two locking docking assemblies are locked and unlocked at the same time, and maintaining the synchronization of unlocking and locking.

[0073] It should be noted that the above example is based on the introduction of two first threaded rods 401 as an example. Those skilled in the art can understand that when there are more than two, the matching relationship between the components remains unchanged, and other quantities can be set based on the above case. This article will not introduce other quantities.

[0074] In addition, the pitches of the two first threaded rods 401 can also be designed to be different, and similarly, the structures of the worm gear 402 can also be designed to be different. The corresponding moving speeds of the two first locking members 700 are different, and the different positions of the two first locking members 700 on the first threaded rod 401 can also be used to enable the two locking docking assemblies to be locked and unlocked at the same time. For example, during the locking process, one of the first locking members 700 with a faster moving speed is farther away from the second locking member 800, while the first locking member 700 with a slower moving speed is closer to the second locking member 800, and the simultaneous locking function can also be achieved. Whether the unlocking function is synchronized can be ignored, as long as all the locking docking assemblies are fully unlocked.

[0075] In a specific embodiment of the present invention, a guide rod for guiding the first locking member 700 is provided on the assembly platform body, the guide rod is arranged in parallel with the first threaded rod 401, and a guide hole for slidingly cooperating with the guide rod is provided on the first locking member 700. In addition to guiding the movement of the first locking member 700, the guide rod can also achieve a limiting function for the first locking member 700 through its cooperation with the guide hole, thereby preventing the first locking member 700 from rotating with the first threaded rod 401.

[0076] Those skilled in the art may select the number of guide rods according to requirements. For example, the number of guide rods corresponding to each first locking member 700 may be two, and the two guide rods may be symmetrically arranged on both sides of the first threaded rod 401 .

[0077] In this embodiment, the stowed position of the rack 300 can be designed to be in a state where the rack 300 rotates toward the support leg 200 to a naturally drooping state. Although this state can avoid occupying space in the height direction, during transportation, since the rotation of the rack 300 is not locked, it will swing back and forth around the hinge axis during transportation to collide with the support leg 200.

[0078] In order to overcome the above problems, Figure 2 As shown, a magnetic member 600 may be provided on the placement rack 300. A magnetic member that is adsorbed to the magnetic member 600 on the placement rack 300 may be provided on the support leg 200, or the support leg 200 may be a magnetic material that can be adsorbed by the magnetic member 600 on the placement rack 300, such as an iron material. When the placement rack 300 is in the retracted position, the magnetic member 600 on the placement rack 300 can be adsorbed to the support leg 200 or the magnetic member on the support leg 200. In this way, when the placement rack 300 is in the retracted position, the magnetic member 600 provided thereon can be used to temporarily fix the placement rack 300 to prevent it from swinging during transportation and colliding with the support leg 200.

[0079] In order to increase the use area of ​​the assembly table 100, in a specific embodiment of the present invention, as shown in FIG. Figure 2 and Figure 5 As shown, the foldable electrical assembly table may further include an extension mechanism 500 , which is disposed on the assembly table top 100 to expand the area of ​​the assembly table top 100 .

[0080] Further, such as Figure 6As shown, the extension mechanism 500 may include an extension plate 506 and an extension adjustment mechanism. Among them, both sides of the assembly table top 100 are provided with extension hidden grooves, and the extension plate 506 can be slidably arranged in the extension hidden grooves. The two sides of the assembly table top 100 are two side surfaces perpendicular to one end where the placement rack 300 is arranged. The assembly table top 100 is a rectangular plate, which has four sides, one of which is used for articulating the placement rack 300. During training or production, the user stands on the side opposite to the articulated placement rack 300. The other two sides are provided with extended hidden grooves, and extension plates 506 are arranged in the extended hidden grooves. The extension plates 506 can be completely hidden in the extended hidden grooves, or partially exposed outside the extended hidden grooves. The exposed portion has the same function as the assembly table top 100, which is equivalent to increasing the use area of ​​the present invention (i.e., the area of ​​the assembly table top 100 itself plus the area of ​​the exposed portion of the extension plate 506) to facilitate the assembly of electrical equipment of different sizes, so that when the present invention is in use, the use area of ​​the present invention can be adjusted according to the size of the electrical equipment.

[0081] The overhang adjustment mechanism is used to drive the extension plate 506 to slide along the extended hidden groove. The extension plate 506 can be controlled to move along the extended hidden groove through the overhang adjustment mechanism, thereby adjusting the area of ​​the extension plate 506 overhanging the extended hidden groove.

[0082] In a specific embodiment of the present invention, the overhang adjustment mechanism may include a rotating rod 501 and a second threaded rod 505. The rotating rod 501 may be rotatably supported on the assembly table 100, and may be supported on the assembly table 100 by a bearing.

[0083] A first bevel gear 503 is provided on the rotating rod 501 . At least one end of the rotating rod 501 extends outward from the assembly table surface 100 . A second rotating hand wheel 502 may be provided on the end of the rotating rod 501 extending outward from the assembly table surface 100 . The rotating rod 501 can be easily rotated by the second rotating hand wheel 502 .

[0084] The second threaded rod 505 is rotatably supported on the assembly table surface 100, and specifically, can be supported on the assembly table surface 100 by a bearing. The second threaded rod 505 is arranged vertically with the rotating rod 501, and the second threaded rod 505 is provided with a second bevel gear 504 meshing with the first bevel gear 503. Through the meshing of the first bevel gear 503 and the second bevel gear 504, the second threaded rod 505 can be arranged vertically with the rotating rod 501, and power transmission can also be achieved. Moreover, the second threaded rod 505 is arranged vertically with the rotating rod 501, which is more conducive to the arrangement of the two on the assembly table surface 100.

[0085] The extension plate 506 is provided with a threaded hole 509 threadedly matched with the second threaded rod 505. The second threaded rod 505 is threadedly matched with the threaded hole 509 of the extension plate 506. By rotating the second threaded rod 505, the extension plate 506 can be moved, and the moving direction is related to the rotation direction of the second threaded rod 505.

[0086] The end of the rotating rod 501 extending outward from the assembly table 100 has a second rotating hand wheel 502. When the user needs to expand the use area, the user can rotate the second rotating hand wheel 502 to drive the rotating rod 501 to rotate. The rotating rod 501 meshes with the first bevel gear 503 and the second bevel gear 504, so that the second threaded rod 505 rotates accordingly. At the same time, the extension plate 506 moves outward along the extended hidden groove under the rotation of the second threaded rod 505 until the area of ​​the exposed part meets the requirements, and then stops rotating the second rotating hand wheel 502. Accordingly, when the user needs to reduce the use area, he only needs to change the rotation direction of the second rotating hand wheel 502 to achieve the action of moving the extension plate 506 into the extended hidden groove.

[0087] Furthermore, in order to improve the stability of the extension plate 506 when it moves, the extension adjustment mechanism may further include a slide bar 507, which is fixed in the extended hidden groove, and a slide bar hole 508 is provided on the extension plate 506 to slide with the slide bar 507, and the slide bar 507 is arranged in parallel with the second threaded rod 505. The slide bar 507 can be used as a guide rod when the extension plate 506 moves, so as to avoid the problem of the second threaded rod 505 and the threaded hole 509 being stuck due to deflection during the movement of the extension plate 506.

[0088] Two slide bars 507 may be arranged corresponding to each extension plate 506, and the two slide bars 507 may be symmetrically arranged on both sides of the second threaded rod 505.
